Abstract

“Extended Bristles” is a application tool that replaces a standard nail polish brush and cap to obtain the complete contents of nail polish by pushing the top plunger cap, which slides over a spring and lower cap and immerses the bristles to the bottom of the bottle. The plunger cap which is attached to the plunger shaft and bristles has a spring located between upper and lower cap around the plunger shaft that retracts when application is completed. The brush is able to extend to the bottom of the bottle when the cap is closed securely or when it is resting unsecured at top of polish bottle. By using the entire contents of the bottle of nail polish the only remaining part is the glass bottle which will not pollute the ground or environment.

Claims

exact text as granted — not AI-modified
1. A nail polish applicator comprising:
 a container having a throat for containing nail polish therein and 
 a cap for closing the container, said cap comprising: 
 an upper plunger cap; 
 a base cap threadedly secured to the throat of the container wherein the upper plunger cap has a hollow portion that at least partially surrounds an outer surface of the base cap such that the upper plunger cap is slidably disposed over the base cap; 
 a seal disposed in the base cap for sealing the container; 
 a plunger shaft having an upper end secured to an inner surface of the upper plunger cap and a lower end having a nail polish applicator attached thereto; and 
 a spring positioned between the inner surface of the upper plunger cap and an upper surface of the base cap; 
 wherein the plunger shaft extends through the spring, base cap and seal such that when the base cap is fully threaded onto the throat of the container and the upper plunger cap is depressed, the upper plunger cap slides along the outer surface of the base cap and thereby depresses the plunger shaft such that the applicator extends to a bottom inner surface of the container and wherein when the base cap is unthreaded from the container and resting on the throat of the bottle and the upper plunger cap is depressed, the upper plunger cap also slides along the base cap and thereby depresses the plunger shaft such that the applicator extends to the bottom inner surface of the container.
